Ophthalmic examination system

Abstract

According to an ophthalmic examination system of an embodiment, a user interface of an examination instruction apparatus is used to enter an instruction for examination. A first communication unit sends the instruction to an ophthalmic examination apparatus in real time. An examination optical system of the ophthalmic examination apparatus includes an optical element applied to an eye and a projection system that projects an examination light beam onto the eye through the optical element. An information presentation optical system includes a display and a light guide system that guides a display light beam from the display to the eye through the optical element. A second communication unit receives the instruction from the examination instruction apparatus. A controller displays the instruction received by the second communication unit on the display in real time.

 when the second communication unit receives the instruction, the controller controls the display to display the instruction together with the examination information. 
 
     
     
       4. The ophthalmic examination system of  claim 3 , wherein the examination information includes a visual target used for visual acuity test of the eye. 
     
     
       5. The ophthalmic examination system of  claim 2 , wherein
 at least part of the examination optical system and at least part of the information presentation optical system share a common portion, 
 the display is configured to display examination information used in examination of the eye, 
 the projection system of the examination optical system is configured to project an examination light beam output from the display, which is displaying the examination information, onto the eye, and 
 when the second communication unit receives information including at least one of the moving image and the instruction, the controller controls the display to display the information together with the examination information. 
 
     
     
       6. The ophthalmic examination system of  claim 5 , wherein the examination information includes a visual target used for visual acuity test of the eye. 
     
     
       7. The ophthalmic examination system of  claim 1 , wherein the controller is configured to set display size of the instruction based on at least one of visual acuity score and refractive power of the eye obtained in advance. 
     
     
       8. The ophthalmic examination system of  claim 1 , wherein the controller is configured to display at least one of text information and image information for supporting examination of the eye as the instruction. 
     
     
       9. The ophthalmic examination system of  claim 1 , wherein
 each of the ophthalmic examination apparatuses further includes an audio output unit configured to output audio information, and 
 when the instruction includes audio information, the controller controls the audio output unit to output the audio information in real time. 
 
     
     
       10. The ophthalmic examination system of  claim 1 , wherein
 each of the ophthalmic examination apparatuses further includes an input unit for inputting a message from a subject,
